.. _auto_curves_average:

*AVERAGE TWO OR MORE CURVES*
============================

Computes the element-wise average of two or more input curves into a single output curve. Accepts a base curve plus one or more additional curves, optionally synchronising their X-axes before averaging. Use this worker whenever you need a mean envelope or corridor centre-line from a set of time-history or XY curves.

Inputs

     - Required
     - Description
   * - Base Curve
     - base_curve
     - vector
     - —
     - 
     - One or more base XY/time-history curves (vector format) that form the starting set for averaging; accepts multiple curves simultaneously — leave unconnected only if all curves are supplied via the repeating 'Curve to be added' port.
   * - Curve To Be Added
     - curvetobeadded
     - vector
     - —
     - 
     - Additional XY/time-history curve(s) to include in the average alongside the base curve; this port repeats so multiple extra curves can be wired in one by one — optional if the base_curve port already carries all curves to be averaged.

Outputs

   * - curves_average_output_1
     - curves_average_output_1
     - vector
     - Single averaged XY curve (vector) whose Y values are the element-wise mean of all input curves at each X location; X extents are determined by the synchronisation setting applied during averaging.
